Logged in cache not working

I have two sites on my Litespeed server and both have your plugin installed. For the one site, cache logged in users works fine, but not for the other. They use the same theme and many of the same plugins. Cache works for both, just that cache for logged in users does not work for one of them. It appears it worked for a very short time when I tested it in incognito mode and logged in, but not anymore.

Any suggestions? I deactivated a bunch of plugins and nothing worked. I recreated the htaccess file but it didnt work either.
